Beit known that I, ARNOLD ZUKOR, a citizen of the United States, and resident of the city `of New York, in the county of Bronx and State of New York, have invented certain new `and useful Improvements in Door- Securing Means, of which the following is a specification.

The present invention relates to improvements in means for securing a door against forcible entry, and has :tor its `main objectto providea device o'lfthis type which may be easily and quickly applied.

Another object of the invention is to provide a device of the type lmentioned which permits of a locking of the door from the outside, the construction being thus particularly adapted for use in connection with stores, lofts, etc., although not limited to that use. p y A .further objectoi' the invention is to pros duce a door securerl `which acts at the same `time as a burglar alarm.

` NVith these and other objects in view, -which will more fully appear as the nature oi the invention is better understood, the same consists in the combination, arrangement vand construction of parts hereinafter described, pointed out in the appended claims yand illustrated in the accompanying drawings, lit being understood that many changesmay ibe made in thesize and proportion ofthe several `parts and details of construction within the scope of lthe appendid claims, without departing from the spirit or sacricing any of the advantages ot the invention.

Oneof the many possible embodiments of the invention is illustrated in the accompanying drawings, in which Figure 1 is a side elevation of the improved d-oor securer, shown applied to a door; Fig. 2 is a front elevation of a guide attached to the inner 'face of the door and a lock co-operating therewith; Fig. 3 is a side `elevation of the elements shown in Fig. 2; Fig. 4 is a section taken on Vline 4-4 of Fig. 2; Fig.y 5 is a ,front elevation, on a larger scale, of vthat portion of the door seeurer which (1o-operates with the guide shown in Fig. 2; F ig..6 is a side elevation, partly in section of the elements shown in Fig. 5; Fig. 7 is a top plan view of a Hoor abutment `cooperating with the securing` Serial No. 637,728.

means shown in Figs. 5 and 6; and Fig. 8 is a section taken on line 8-8 of F ig. 7.

In the drawings, the numeral 10 indicates a portion of a door and the numeral 11 the floor or passageway, entrance into which is effected through the door. To secure the door against forcible entry, a longitudinally yielding bar 12 is provided, said bar being made of two sections, lthat is to say an uppz-r section 18 and a lower section 14, the upper section having attached to its lower end, or made integral therewith, a piston 15, which is slidably disposed in a cylinder 16 upon the upper end of the lower bar section 14. A spring 17 is disposed within the cylinder, its purpose being to hold the upper bar section 13 in itselevated position. In order -to prevent the piston 15 from turning in the cylinder 16, there is attached to one of these elements, for instance to the piston 15, a pin 18, projecting through a longitudinal slot 19 in the cylinder. The pin and slot limit at the same time the vmovement of the piston `in the cylinder, the pin having also another purpose, which will be presently described. To the cylinder is Iattached a :bell 20, preferably, a rotatable bell, containing a .suitable mechanism, such as a hammer and actuating mechanism therefor, whereby, lwhen the bell is released and` allowed to be krevolved by the usual spring motor, the .bell is sounded. Vith the escapement of `the motor of this bell `co-operates a stop 21, that is disposed in opera- .tive relation .to the pin 18. The lower end oic the bar section 14 is made in the form ot `an eye 22 and is adapted to be hooked into an abutment 23 on the Hoor, said abutment being of suiiicient strength .to resist the thrust .of the bar. This .abutment comprises a plate member-24 which is sunk into the floor, its upper face `being flush with the floor, held in position by screws or otherwise. In this plate member are formed two 4recesses 25, into which are yadapted to be fitted the ends of a U-shapedl member 26, that hasbeen hooked into the eye 22, a suitable mechanism, in the form of a latch 27 of any suitable construction, co-operating with the said hook to `-hold it in position on the plate member `24. This latch is pivot ed, for instance, at 28 to the ,plate member and is adapted to be 4inserted between two lugs 29 on one of the Shanks of .the'Ushaped the bar section 13.

rl`he llock is slidably disposed in a guide 33, that is iXed to the inner face of the door 10, the said guide being made in the form of a rchannel iron, as clearly shownv in Fig. 4

l, of the drawings, which is disposed vertically `lower ends of the said sides.

on the door. The channel iron is provided on its sides 34 with inwardly projecting anges 35, which are spaced from the body portion 36 of the channel iron and extend substantially parallel thereto, preventing a disengagement of the lock 32 from the channel iron, the upper and lower ends of the latter being closed by heads 37 and 38, respectively.

The lock may beef any suitable construction, its main feature being that it includes two spring-pressed bolts 39, that is to say bolts which are projected by springs to locking positions. These bolts are disposed upon opposite ends of the lock casing and are adaptedl to cofoperate with openings 40 in the sides 34of`the guide 33, said openings being in registering positions adjacent the The lock is provided both in its front and rear faces with keyholes 41, the keyhole in the rear face of the lock, that is to say in that face which abuts against the inner face of the body portion 36 of the guide 33, being adapted to register with keyholes 42 in the said body portion and door, more particularly when thevlock is in its lowermost position in the guide, as clearly shown in Fig. 1 of the drawings.

A screw 43 is extended through one of the sides 34 of the guide 33 adjacent the lower end of the latter, which screw serves to secure the lock 32 in itslowermost position, for a purpose hereinafter to be described.

On the inner faces of the sides 34 of the guide are provided in registering positions inwardly projecting lugs 44, a little distance above the lower end of the said guide, with which are adapted to co-opeiate the locking bolts 39 of the lock, as the latter slides from its lowermost position vto its uppermost position.

The operation of the door securer is as follows: When the device is not in use, the bar section 14 is disengaged from the U- shaped member 26 and the bar 12, as a whole,

swung around the pivot pin on the lug 31 into parallel relation to the door and held in such position by any suitable means, not

shown. Then the door is to be secured against forcible entry, the ends of the U- shaped member 2G are seated in the recesses 25 in the plate member 24 and the latch 27 shifted into engagement with the lugs 29 on one of the shauks of the said U-shaped member. The door being partly open, the lock 32 is in its uppermost position, t uit is to say adjacent the head 37 on the guide 33, its locking bolts 39 being held against the action of the springs co-operating therewith in their retracted positions, abutting against the inner faces of the sides 34 of the said guide. As now the door is closed, either from the inside or from the outside, the lock slides in the guide downwards until its bolts register with the openings 40 in the sides of the guide, when, under the action of the springs, they are projected into the said holes into the positions shown in Figs. 1 and 2 of the drawings, the door bein thus securely held against forcible entry. f the person securing the door remains within the room, additional security ma be obtained by turning the screw 43 in tie proper direction so that it abuts against one of the sides of the lock casing, whereby even a person holding the )roper key is prevented from opening the oor from the outside. If the screw 43 is not engaged with the lock casing, the door may be opened both from the inside and from the outside b a key. By turning the key in the required diirection, the bolts 39 are retracted from the openings 40 in the sides of the guide 33, after which the door may be opened, and, as it swings inwardly, the lock will move toward the head 37, the lower end of the bar section 14 remaining in engagement with the U-shaped member 26. The extent of the opening movement of the door depends obviously upon the length of the guide 33. In practice this guide is of such length that it permits the door to be opened about two feet. The link 30 is connected in the manner above described with the bar section 13 and the lug 31 on the lock casing to permit of a slight turning movement of the bar 12 both in the upward and downward movement of the lock 32. This slight turning movement is necessary by reason ot the fact that the door and consequently the guide 33 move in an arc, as the door is being opened and closed.

When the lock moves from its lowermost position to its uppermost position, its movement is slightly retarded when the locking bolts 39 thereof ride over the inwardly projecting lugs 44 on the inner faces of the sides of the guide 33. Due to this retarded motion, the piston 15 is depressed against the action of the spring 17, the )in 18 heilig brought into abutment with tI-he stop 21, forcing the same downwards and releasin the escapement of the spring motor of the bell 20, thereby allowing the hammer of the with the upper end of said bar, said guide 'bell to strike and ring the bell, thus indicathaving holes adjacent its lower end for coing that someone is entering the room. The operation With locking bolts of said lock to device acts thus, besides being a securing secure the door against forcible entry. l5 5 means for the door, as a burglar alarm. 2.
